Allopolypoidly can be defined as an organism that has two haploid sets of chromosomes that are not the same and are from two different species. A hybrid species are created which express according to the man-made desires. For example, making the plant pest resistance or increasing yield. In a hybrid species, it contains a different set of chromosomes from two different organisms, a translocation causes a break of one part of the chromosome and attaches to others. This rearrangement causes the hybrid species to lose its integrity and they become sterile. Similarly, inversion is a mutation in which part of a chromosome is inverted and then joined end to end. With this also hybrid loses its property and become sterile. As they may not able to survive this situation as they already have manipulated the system and if it alters they lose their property.

A. Organisms heterozygous for inversions and translocations are
viable and able to produce progeny but usually in fewer numbers.
Explain why this is so in general terms.
B. Also, explain how would you distinguish among pericentric
inversions, paracentric inverisons, reciprocal translocations and
non reciprocal translocations as sources of semi-sterility. You
need to consider meiotic figures.
C. How can these chromosome aberrations be used to map genes to
chromosomes or linkage groups. You may use a two-point mapping
system as an...

Under nearly all circumstances, postzygotic reproductive
isolation cannot evolve under the direct action of natural
selection. Instead, postzygotic isolation evolves as a by-product
of other genetic changes as proto-species diverge. In contrast,
natural selection can directly act to enhance prezygotic
reproductive isolation. Consider two species with overlapping
ranges. If hybrids between the species are less fit than pure
species individuals, females that mated with heterospecific males
would be at a selective disadvantage, because their resulting
offspring had low fitness....

In the discussion, how do the authors explain the fact that
between digoxin and placebo there were no differences in all-cause
mortality but there were in hospitalizations?
A. They don't.
B. They argue that the sample size may not have been large
enough to detect differences in mortality.
C. They point out the fact that they had a borderline
significant finding for mortality due to worsening heart failure
and suggest that may help with heart failure but may cause bone...
